Continuing its effort to stake out turf in a fast-growing area, Google on Tuesday announced the ability of mobile phones to show Google-supplied advertisements through a program called AdSense for mobile search.

Google sells ads next to its own search results through a service called AdWords, but the newer development involves a separate service called AdSense that lets publishers show Google-administered ads on their own sites. Google launched AdSense for mobile phones in 2007, but now it's seeking testers for a hybrid offering that involves others using Google's own search engine.

With it, mobile phone makers or mobile network operators can use Google's search engine and search results, sharing in revenue that comes from the accompanying search ads, Yury Pinsky, product manager of Google's mobile team, said in a blog post Tuesday.

The search can be co-branded with others' Web sites, Google said, implying the company is willing to share but not to let its brand vanish altogether.

Google dominates search for computers, but the company and rivals such as Microsoft and Google are scrambling to stake claims in the mobile market, where increasingly sophisticated phones and networks now permit correspondingly better Web browsing. It's a major new area of growth for advertising companies.
